Introduction

This filter blurs or sharpens an image depending on the sign of "amount". You can either set amount for both luma and chroma or you can set it individually (recommended). A positive value for amount will sharpen the image, a negative value will blur it. A sane range for amount is -1.5 to 1.5. The matrix sizes must be odd and define the range/strength of the effect. Sensible ranges are 3x3 to 7x7. It sometimes makes sense to sharpen the sharpen the luma and to blur the chroma.
